CompTIA Server+ (SK0-005) — Question 97

An administrator is configuring a new server for use as a database server. It will have two mirrored drives to hold the operating system, and there will be three drive bays remaining for storage.

Which of the following RAID levels will yield the BEST combination of available space and redundancy?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 10

Correct answer: C

Explanation

RAID 5 offers a good mix of usable space and redundancy by using striping with parity, allowing for one drive failure without data loss. RAID 0 provides no redundancy, while RAID 1 duplicates data, which limits available space. RAID 10 combines mirroring and striping but requires more drives, reducing available capacity compared to RAID 5.
